This application is a continuation of International Application No. PCT/US2013/021201, filed Jan. 11, 2013, which claims the benefit of U.S. Provisional Patent Application No. 61/673,850, filed Jul. 20, 2012, which is incorporated herein by reference in its entirety.

BACKGROUND OF THE INVENTION

The present invention relates generally to the field of parking meter systems, devices and methods. The present invention relates specifically to a parking meter system equipped for wireless communication.

Single-space parking meters are typically associated with a single parking space. To utilize an individually metered parking space, a motorist typically inserts money into the parking meter, and the parking meter displays an amount of time related to the amount of money inserted. A multi-space meter typically provides a single payment location for more than one parking spot, and the multi-space meter receives payment and tracks meter time for the multiple parking spots. For either type of meter, the motorist may park at the metered spot for the amount of parking time purchased. When the time on the meter expires, the motorist may move their car or add more time to the meter. If the meter expires and the motorist remains parked at the meter, a parking enforcement officer may issue a parking ticket. A city or other entity may operate a city wide system of single-space parking meters and/or multi-space meters.

Curved upper surface 128 is shaped to substantially match the curve of the uppermost surface of inner housing 46, shown as crown 146, and also substantially matches the curve of the inner surface of cap 73. Lateral portion 126 extends downward from a lateral portion of upper portion 124 along a lateral edge of rear display 104. In the embodiment shown, lateral portion 126 extends downward along the right lateral edge of rear display 104.

As shown in FIG. 9, upper portion 124 includes a rear facing vertical surface 130 and a lower, downward facing horizontal surface 132. Vertical surface 130 is generally parallel with rear display 104 and extends downward from and substantially perpendicular from upper surface 128. Horizontal surface 132 extends inward from the lower edge of vertical surface 130 and is substantially perpendicular to the vertical plane defined by rear display 104. The inner edge of horizontal surface 132 is located immediately above the upper edge of rear display 104.

Lateral antenna housing portion 126 includes a rear facing vertical surface 134 and a lateral facing (specifically a left facing) vertical surface 136. Rear facing vertical surface 134 extends downward from and is contiguous and coplanar with rear facing vertical surface 130 of upper portion 124. Lateral facing vertical surface 136 extends toward rear display 104 from an inner edge of rear facing vertical surface 134 and the inner edge of lateral facing vertical surface 136 is located immediately adjacent to the lateral edge of rear display 104. In this arrangement, lateral facing vertical surface 136 is perpendicular to horizontal surface 132 and intersect each other adjacent to the upper right corner of rear display 104. In one embodiment, at least a portion of antenna 66 is located within upper portion 124 and is also located above rear display 104 and/or above rear solar panel 120. In one such embodiment, antenna 66 is completely located within upper portion 124 above rear display 104 and above rear solar panel 120.

In various embodiments, lateral antenna housing portion 126 provides an open space within the antenna housing that facilitates transmission of the signal from antenna 66. Further, lateral antenna housing portion 126 provides a third engagement point on antenna housing 122 that engages fastener 105 at a position adjacent to the lateral edge of display 104. Fasteners 107 and 109 engage upper portion 124 at positions above display 104. Fastener 105 along with fasteners 107 and 109 provide for stable attachment of antenna housing 122 to the rest of the inner housing of meter mechanism 44. In one embodiment, lateral portion 126 provides a protective housing and support for a wired communication link (e.g., a wired connection) that runs from an antenna 66 located within upper portion 124 to the other communications hardware and processing systems located within the main body portion of inner housing 46.

Referring to FIG. 10, a view of electronic meter mechanism 44 located within outer meter housing 42 is shown according to an exemplary embodiment. As shown in FIG. 10, cap 73 is coupled to base 71 such that meter mechanism 44 is enclosed within outer meter housing 42. Meter mechanism 44 is structured such that antenna 66 located within antenna housing 122 is permitted to receive and transmit data from within outer meter housing 42. In one such embodiment, at least a portion of antenna housing 122 and a portion of antenna 66 are located above lower edge 140 of window 74. In one embodiment, at least a portion of antenna housing 122 and a portion of antenna 66 are located below (i.e., at a lower position as measured along the vertical axis of the meter mechanism) upper edge 142 of window 74. In various embodiments, the positioning of antenna housing 122 and of antenna 66 as well as the material of window 74 allows for transmission and receipt of wireless communication signals (e.g., RF signals, wifi signals, cellular telephone signals) through the material of window 74. In various embodiments, the positioning of antenna housing 122 and of antenna 66 allows for transmission and receipt of wireless communication signals (e.g., RF signals, wifi signals, cellular telephone signals) that comply with applicable standards and regulations. In various embodiments, window 74 may be made from a transparent or translucent material (e.g., clear plastic or glass). In one such embodiment, window 74 is made from a strengthened or reinforced transparent or translucent material that resists breaking. Further, the arrangement of antenna housing 122 described above provides for space within inner housing 46 in which to hold antenna 66 while providing an unobstructed view of rear display 104.
